摘要:

研究了极性和非极性吸附树脂在水和非水体系中对苯胺、N-甲基苯胺、N, N-二甲基苯胺的吸附规律,结果表明,含酯羰基的极性树脂在非极性体系中对3种胺的吸附顺序为苯胺、N-甲基苯胺、N,N-二甲基苯胺,吸附机理应与氢键的形成有关;在水体系中,吸附顺序相反,这与3种胺的疏水性有关.用含酯羰基的树脂对3种胺的混合水溶液进行动态色层吸附,可将3种胺完全分离,此结果预示用吸附树脂对生物减进行常压色谱分离是有可能的.

Abstract:

The static adsorptions of aniline, N-methylaniline and N, N-dimethylaniline onto ADS-17 in nonpolar solvent and water were studied. The results show that in nonpolar solvent, the adsorption sequence was aniline, N-methylaniline and N, N-dimethylaniiine. The adsorption mechanism relates to the form of hydrogen-bonding. But in water the adsorption sequence was opposite. This appreciates to hydrophobic interaction. In water those three amines could be isolated by dynamic chromatographic separation with the polycarboxylic ester sorbent. The results indicate the feasibility of chromatographic separation of alkaloid in normal press using special resin.

Key words: sorbent, amine, chromatographic separation
